Speed, Velocity, & Acceleration Practice

Front

What is positive acceleration?

Back

Positive acceleration is when the object is speeding up.

Front

What is negative acceleration?

Back

Negative acceleration is when the object is slowing down.

Front

What is the difference between positive and negative acceleration?

Back

Positive acceleration is when the object is speeding up and negative acceleration is when the object is slowing down.

Front

What is a magnitude?

Back

A magnitude is a numerical measurement.

Front

Is my car accelerating if it goes from 5 m/s to 0.5 m/s?

Back

Yes, because the speed is changing.

Front

What is the formula for speed?

Back

Speed = distance ÷ time.

Front

What is the speed of a car that travels 400 m in 20 minutes?

Back

20 m/min.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity.

Front

If a cat moves at a constant rate of 6 m/s for 3 seconds, what is its acceleration?

Back

0 m/s².

Front

What does it mean if an object has a constant speed?

Back

It means the object's speed does not change over time.
